The PKP Development Team is pleased to announce the release of OHS 2.3.0.

This is a major rewrite of numerous parts of the Harvester code, including metadata storage and indexing. It increases indexing flexibility to support plugin-based indexing, including Lucene/SOLR support. It also adds OAI Data Provider support, including the potential to convert between metadata formats (currently from various formats into Dublin Core).

OHS 2.3.0 is available at http://pkp.sfu.ca/harvester_download.

Because of the extensive changes in metadata storage, note that the upgrade process deletes stored metadata and all archives will need to be re-harvested following the upgrade.
